InstallAware

I've just bought the license for InstallAware Express x10. Prior to licensing the product my project would build an MSI as a single file just fine. After downloading and running the licensing application it is now trying to configure Visual Studio 2008 shell, which I can't download and is no longer available? Why has this started happening? As a result my build no longer works and I can't generate an MSI.

Any help would be greatly appreciated!
